Runescape tends to fly along under most people's radars. Maybe because it's free, maybe because it's browser-based, maybe because of both. Doesn't matter! Game's still insanely popular.

Publishers Jagex have revealed that the game has had 105 million people sign up since launching eight years ago. Sure, it's free to sign up, and there'll be multiple accounts among that figure, but still. It's an impressive number.

Not as impressive as the game's active user base, though, which is a far more accurate way to gauge the health of an online game. Jagex say that, depending on whether you're "taking a day, a week, three months", Runescape has 10 million active players.
